Flutter: Gradle build failed to produce an .apk file. It's likely that this file was generated under <app_root>\build, but the tool couldn't find it

Question

I am trying to test drive an app. I keep getting a strange issue with this problem as app fail to debug/run. SDK version is 28 while the rest is below:

Flutter 1.13.9-pre.79 • channel master • https://github.com/flutter/flutter.git Framework • revision 9eb9ea0ffa (6 hours ago) • 2020-01-13 21:30:42 -0800 Engine • revision 0235a50843 Tools • Dart 2.8.0 (build 2.8.0-dev.0.0 28c335d5a2) 

Gradle build failed to produce an .apk file. It's likely that this file was generated under C:\Development\\build, but the tool couldn't find it.

Is there a way to pass this issue or a configuration that can allow me to run by providing or giving the output path to Gradle? The .apk seems to generated as the error states.

UPDATE:

Android Studio -v 3.5.3  Gradle -v 3.4.2  Gradle Wrapper -v 5.1.1 

Answer 1

in my case I have a multi flavor app like this:

{     // Use IntelliSense to learn about possible attributes.     // Hover to view descriptions of existing attributes.     // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387     "version": "0.2.0",     "configurations": [             {                     "name": "YOUR_PROJECT_NAME",                     "program": "lib/main.dart",                     "request": "launch",                     "type": "dart",                     "args": [                             "--flavor",                             "ADD_YOUR_FLAVOR_NAME_HERE" //development or staging or production                         ]             }     ] 

Another way:

 android {      ...      buildTypes {         release {             // TODO: Add your own signing config for the release build.             // Signing with the debug keys for now, so `flutter run --release` works.             signingConfig signingConfigs.debug         }     }      flavorDimensions "flavor-type"      productFlavors{         development{             dimension "flavor-type"         }         staging{             dimension "flavor-type"         }         production{             dimension "flavor-type"         }     } } 

So if you want to run app you have to write the flavor name and then the class name that hold main() function

flutter run --flavor staging -t lib/main_staging.dart 

and I solved my error and built the .apk

Answer 2

Added the flavor name in Build name from Edit Configurations and it worked!
